PRODUCTION DATA
The DS160PR421 receivers feature a continuous-time linear equalizer (CTLE) that applies high-frequency boost to help equalize the frequency-dependent insertion loss effects of the passive channel. #GUID-9690E2DC-7AF3-406B-A9BB-BA4D2C99CB37/T5706319-21 shows available equalization boost through EQ control pins (EQ1 and EQ0), when in Pin Control mode (MODE = L0).
